METHOD OF RANDING HEEL BLANKS.

Application filed November 7, 1923.

eral object the provision of a novel method of procedure by following which the rands may be applied to and secured on the heel blank with ease and rapidity, and with resultant uniform excellence in product.

In devising my method, I also have specifically in mind obviating certain unavoidable defects, or disadvantages,v in operation which have characterized methods heretofore practiced, and particularly those involved in a certain method which consists in placing the pasted rand on a heel blank in a holder, forcing a pressure device againstthe rand, bending the rand into a heel shape on the heel blank beneath the pressure device and against its resistance, and then forcing the pressure device against the rand with suflicient power to secure it to the heel blank and to force the blank into the holder.

This former method of randing is the subject of a pending application filed in the interest of and owned by the same company to which the present application has been assigned, and, while relativelysuccessful, has two serious disadvantages: First, when the heel blank, because of a curvature, bump, wrinkle or other character of defect, does not lie flat in the holder so that its upper surface will lie flush with the top of the holder, the rand cannot be forced into position except with considerable difiiculty. If, for instance, some part of the heel blank projects above the top of the holder, the rand, in being wiped into position, will catch on that part of the blank and will be n'eventedfrom assuming its proper position. Again, if part of the outer edge of the heel blank should turn down into the holder, insteadv of being flush with its upper edge, the rand will not slide in smoothly as it should, but will roll under at its inner Either.

tion of the. machine, especially when the stock to he landed consists of single lifts, which, are, by nature, flimsy and curved, or otherwise of uneven surface.

The, second disadvantage of the former method resides in the fact that the rand, after it has been forced down in the holder with the blank, will sometimes spring up outof the holder instead of adhering to the blank as it, should. Since the randis shaped, in the first place, from a straight piece of leather, its. tendency, of course, when brought into a heel shape, is to spring outward. hen it is driven down into the holder, this tendency to spring outward makes it bind against the sides of the holder and ordinarily keeps it in the proper position. If, as is frequently the case, the stock or blank-underneath it is springy, a part of the rand will sometimes be forced up out of the holder and be permitted to spring out of position. This is very inconvenient, because once the rand is sprung out of the holder, it cannot conveniently be put back again by hand, and before it can be put back by operating the machine, an extra lift must be inserted so as again to present a flush surface with the top of the holder. My present method avoids both of these disadvantages: that is, the difiiculty of randing uneven lifts or blanks, and the tendency of the rand to fly out of the holder.

According to the present invention, the rand is shaped to position on an iron plate and not to a heel blank or lift, and the difficulty of wiping it intoplace is overcome. This is because these plates are smooth, even, uniform in thickness, and always lie flat and in the same place in the holder. Qonsequently, exactly the proper clearance space is provided between the plate and the pressure device for the incoming rand, and the latter may be wiped into position-without encountering any obstruction whatsoever. Again, the present invention avoids the annoyance and delay resulting from the rand springing out of the holder after being forced downward therein, because the rand has under it, not a springy piece of stock as in the former method, but an iron plate. There is, therefore, no tendency in the present case to force the rand upward out of the holder.

As the operation proceeds, each heel blank in the holder will be held firmly in position between two metal plates, the under neath plate presenting a curved surface shaped exactly to the concavity of the randed heel, and the upper plate present "ingits flat surface to the flat surface of 'the heel. {pressure as it passes through the holder Thus, each heel receives an ideal and the log container, and emerges superior, both in appearance and solidity, to the randed heel produced by the former method.

Stated succinctly, my improved method resides in first inserting in the holder a metal plate having its underneath side flat and its upper side convex, and presenting a downwardly inclined marginal portion, in placing on the upper side of this plate at its rear end a rand, and temporarily holding the rand in place on the plate by applying pressure to the central portion thereof, then bending, or wiping, the end portions of the rand into heel shape on the plate, and forcing the rand with the plate downward in a heel-shaped holder,then applyingpaste to the. marginal portion of a heel blank and placing saidheel blank on the rand, and, finally, applying pressure to the heel blank to force it into engagement with the rand and to force the resultant randed heel blank with the plate on which it rests downward in the holder. Continuing the operation, to form successive randed heel blanks, the plate is next applied to the flat surface of the previously randed heel blank, and the preceding operations repeated.

Owing to the shape of the metal plates employed, conforming to the shape of the randed surface of the heel blank, the appli cation of pressure to the successive heel blanks and to the column of heel blanks in the holder results in a molding operation in which the rand is evenly and uniformly pressed into position on the heel blank and the crimps and other unevenness in the rand substantially completely flattened out, so so that when the randed heel blank emerges from the bottom of the log holder, it has, in all essential respects, the appearance of a randed heel blank which has been sub jected to great pressure in the ordinary compress used for this purpose.

Having thus stated the general objects of my invention, and the advantages incident to the use thereof, I will now proceed to describe the same in detail iii connection with the machine which I prefer to employ in the practice of my method. This machine is illustrated in the accompanying drawings, in which- Figure 1 is a view in front elevation of the machine which I prefer to use in practicing my method;

The machine illustrated herein embodies, in all essential respects, the principle of operation of the lift-cutting machine described and claimed in the patent to Parks, No. 1,297,899, dated March 18th, 1919, and is also substantially the same in construction as the machine illustrated and described; in the pending application of Parks, Serial No. 658,853, filed August 23rd, 1923, which application is directed to the prior method above alluded to, and certain disadvantages of which it is the object of the present invention to overcome. The present machine, however, is shown provided with a handoperated tripping device in place of the automatic device of said application, although it is possible to use an automatic trip of a different type from that illustrated in the Parks case referred to, and, in actual practice, such is used; as the machine, however, forms no part of the present invention, I have, for the purpose of simplicity, shown a hand-operated trip, as stated.

l will first briefly describe th machine herein illustrated, and then the manner of practicing my method. by using the same.

The machine comprises a frame consisting of side members 1, connected by frame bars 2, the lower portion of the side frame members being provided with legs, or standards, 3, on which the machine rests. Mounted centrally of the frame of the machine is a log-holder 4: of the usual construction, the upper end of which is secured to the underside of a table or bed 5, on either side of which are mounted bins 6 for receiving the heel blanks to be randed. Secured on the table in alinement with the log-holder 4-. is a heel blank holder 7, for receiving, in succession, the heel blanks to be randed. This holder is secured on the upper side of the table 5, and the latter rests upon the upper ends of adjusting screws 8, by turning which, in one directien or the other, the holder 7 may be adjusted to the proper height relative to the movement of a presser foot 9. This, presser foot is mounted centrally of a cross-head 10, which slides on ways 11, provided on the inner sides of the side frame members 1.

Mounted in the upper ends of the frame members 1 is a shaft 12 (Figure 2), on which is a fast pulley 13 and a loose pulley 14-, a belt (not shown), driven from any suitable source of power, being movable through the medium of a belt shifter 15 to either of said pulleys, in the usual way. Mounted on the shaft 12 are two cams 16. Mounted above the cross-head 10 to slide on the ways 11 is a frame plate 1'7, which has mounted in its upper ends (Figure 2) a cross-shaft 18, which affords bearings for rollers 19, which are normally in engagement with the cams 16. Such enga ement is maintained through the medium of springs 20, secured at t eir upper ends to the frame plate 17. this plate, with the parts mounted thereon, as hereinafter described, is adapted to be continuously reciprocated by the co-action of cams 16 and springs 20 as the shaft 12 is rotated, the springs 20 maintaining the rollers 19 in contact with the cams 16 at all times, and yielding to allow the plate to be lowered under the action of said cams;

Pivotally mounted on the frame plate 17 is an actuating plate 21 (Figures 1, 2 and 3), this plate having lugs 22 projecting from its rear side at the top, which extend through apertures 23 of the frame plate 17. At either side, at its upper end, the plate 21 is provided with cars 24 (Figure 1), over which engage coil springs 25, the lower ends of which are secured to the lower end of the frame plate 17.

Provided on the front of the cross-head 10 is a shouldered projection 26, and when the cross-head 10 is lowered, the actuating plate 21 is adapted to have its lower edge moved into and out of engagement with the shoulder 26 to depress the presser foot by the action of the machine. For this purpose, there is pivotally mounted centrally of the plate 17 a dog 27. The lower end of dog 27 is normally drawn inward or toward the plate 17 by means of coil springs 28, cured at their lower ends to the frame plate, and their upper ends to projections 29 on 7 cross-head 10 and presser foot 9 in the i r The presser foot 9 and cross-head l lowered through the medium of rod connected at their upper ends to brackets (Figure on the lower end of the crosshead 10 and connected by treadles 32?, one or the other of which may be used according as it is more convenient for the operator.

Coil springs are connected at their lower ends, respectively, to the rods 32, and

their upper ends to the frame of themachine, which tend normally to raise the rods 32 and treadles 8d and thereby hold the vated position. The presser foot 9 is of special construction, and the same will new be described, referring particularly to Figures 3, 4 and f,

The said presser foot comprises'a casting 36 which is recessed on its upper side to receive a foot-piece 37 on the lower end of the cross-head 10 to which it is secured by set screws 38. At its front, end, the casting 36 has a downwardly depending portion 39, to which is secured a brass plate 4+0, which is bent at right angles to extend over the bottom edge of the depending portion 39, as indicated at 41, the latter serving as a cutting block to engage the cutting'edge of a cutter 45:2 mounted in the front wall of the holder 7. Secured on the underside of the top of casting 86 is a curved or Urshaped member 43, the opposite walls or legs of which are slotted, as indicated 4e. Loosely mounted on and surrounding he member 43 is a heel-shaped member 45, which operates, first, as a rand-holder, and then, with the member 13, as a plunger or presser foot to press the rand firmly against a forming plate and simultaneously force these parts downward in the holder- 7. The member a5 is supported by a pin 46, W1 ic passes through the slots 44 and is secured in the walls of the member 15.

As shown by Figures 3 and 5, the front or breast side 4L7 of the member 15 is of less height than the remainder of said member, and the walls of the U-shaped member 43 are cut away to form projections 48, which extend over the front wall 47 at a distance therefrom. The upper edge of the remaining portion of the wall of member 45 is normally positioned at some distance below the underside of the top of casting 36, and the lower edge of member 15 extends below the lower edge of member 43. Thus, when the presser foot, as a whole, is moved downward, the lo ver' edge of the member 4-5 will first engage the rand, and, afterward, the U-shaped member l?) wlll move downwardly into engagement wlth the rand. The

member 45 falls to the lower position shown eleby gravity and is raised against the resistance of a coil spring 49 interposed between the casting 36 and the pivot pin 46. The manner of mounting the member allows the same to rock slightly on the pivot pin 46, as will be understood.

In proceeding to rand a heel blank according to my invention and with the use of the present machine, the rand strip is first placed on a heel-shaped metal plate and held atits center at the rear of the plate by the member 45, as hereinafter explained, and then the shaping device is manipulated to force the side portions or legs of the rand into position on the plate between the latter and the presser foot.

The plate I employ is shown in Figure 6 and indicated by the numeral 49 As stated, this plate is heel-shaped and has a fiat underside 50 and a convex upper side formed by beveling the marginal portion of the plate, as indicated at 51.

The mechanism for shaping the rand, or wiping it into position on the forming plate, will now be described, referring more particularly to Figures 5, 7 and 8.

Projecting from the rear of the holder 7 is a flat support 52 which, likewise, projects laterally from the sides of said mold, as shown more particularly in Figure 7. The edges of this support are inclined or undercut, as indicated at 53 in Figure 4, and slidably mounted on this support is a Slide plate 54 which is in the form of a plate I provided in its forward edge portion with a heel-shaped recess 55, and at its forward end, at opposite sides, with handles 56. On its underside, the plate 54 is provided with a groove 57 which embraces the inclined edges 53 of support 52. By grasping the handles 56, the plate 54 may be slid back and forth on the support 52, as will be understood.

The numeral 58 indicates a stop, which is provided on the support 52 adjacent the edge of the holder 7. In practice, this stop serves to assist the operator in positioning the rand on the heel blank.

In operation, the rand, being placed in position on the plate 49*, as shown in Figure 7, the operator presses down on treadle 34 to bring the holding member 45 of the presser foot into engagement with the rand and hold it in that position while the slide plate or shaper 54 is pulled forward to force the ends of the rands into heel shape, as shown by Figure 8.

The rand is curved or rounded at its rear side instead of being given an abrupt bend by providing a plurality of short pointed projections or spikes 59 (Figures 3 and 4), on the bottom of the presser foot, the drawing showing four of such spikes. Two or three spikes, however, might serve, the object being to grip the rand at at least two points beyond its center 01' point of bending so as to compel the rand to curve at its center under the action of the shaper instead of bending abruptly. In other words, the rand is thus bent about two points instead of a single point.

I have referred to the U-shaped or inner member 43 of the presser foot as having its lower edge located above the lower edge of the outer member or heel-shaped holder 45. This position of these parts is shown particularly in Figures 3 and 5, and it will be seen that when the member 45 is in position on the plate, as shown by Figure 5, a space 60 will be provided above the rand, and this space will accommodate the crimped edge of the rand as the latter is turned inward by the shaper, this crimped or inner edge portion tending to buckle up, and, under any circumstances, requiring a space to accommodate it in order to permit the rand to be easily curved into position on the forming plate 49.

In order to permit the shaper 54 to move to a position over the holder so that the inner edge of the recess 55 will correspond with the inner edge portion of said holder, I provide at the center of said recess 55 and on the underside of the slide plate 54 a recess 61 (Figures 4 and 5), which will receive the stop 58 and thus, as stated, will permit the plate 54 to be moved to the correct shaping osition.

The holder heretofore referred to, has, preferably, the size and shape of the heel blank to be randed, and comprises a U shaped wall 62 (Figure 7), corresponding to the rounded portion and sides of the heel blank, and a front wall, corresponding to the breast of the heel blank, the upper edge of which is sharpened to provide a cutter, this wall having'previously been indicated as a cutter by the numeral 42 (Figures 4 and 5). The presser foot 9, as to the members 43 and 45, has its bottom surface flat to conform to the upper surface of the plate 49 with the rand 63 applied, and to the flat surface of the heel blank.

The depending portion, or cutting block,

39 of the presser foot, with its soft metal covering 41, is designed to co-operate with the cutter 42. By turning the adjusting screws 8, the height of the holder 7 may be so regulated that in the downward movement of the presser foot 9, the metal plate 41 will engage the cutter 42 with sufiicient firmness to completely sever any material placed between the said cutting block and cutter.

As shown by Figure 4, the knife edge of cutter 42 is located below the plane of the upper surface of holder 7. This permits a heel blank to be inserted from the front of the holder, and the outer member 47 of the presser foot is of a size to be received snugly into the holder when the presser foot is lowered.

In operation, the metal plate 49 is placed in the holder 7 with its convex side upward, or in" the position shown in Figured A rand is then placed on the plate at the rear or rounded marginal portion thereof with its beveled side downward and flat side up ward, and moved by the operator against the stop 58, in the manner indicated by Figure 7. The operator now places his foot upon treadle 34 and lowers the cross-head 10 and presser foot 9. In this movement, the lower edge of the rear portion of thememher 45 of the presser foot engages the rand 63, the spikes 59 piercing the rand andholding it in position on" the plate. The opera tor now grasps the handles 56 of the shaper 54 and draws the latter forward. In this movement, the corners of the recess which, as indicated by dotted lines in Fig ures 7 and 8 and in full lines in Figure 4 at 65, is undercut, engage the outer edge of the rand and" gradually forces the same utnder the lower edge of the member 45' into position on top of the metal plate, forcing the rand to assume a curved position, as indicated in Figure 8, with the ends 66 of the rand projectingover and beyond the cutter 42.

According to. one'method of practicing my invention, the machine is now tripped manually by .the operator to permit the presser foot to force the rand and plate downward in the holder 7. A heel blank 64, having had paste applied to its flat surface around the marginal portion thereof, is then placed on top of the rand, the recess 55 of the shaper serving as a guide to properly position the heel blank, in this operation. The presser foot is now again lowered and the machine tripped to cause the presser foot to force the heel blank into engagement with the rand and the randed heel blank and plate downward in the holder. A new. plate is then inserted in the holder and the preceding operation repeated".

The application of paste to the heel blank is effected preferably by applying it to a U-shaped dauber covered with paste, such device being shown and described in a pending: application of Dennis Parks, filed of even date herewith.

As stated above, the machine is tripped automatically in actual operation. In the present instance, I have shown a handle" 67 mounted on the dog 27. This handle is grasped by the operator and pulled outward to move dog-27 out of engagement with the lug 31' on the front end of actuatingplate 21. As the downward movement of cross head10 has .opera'tedto carry the projection 26 below the lower edge of the actuating plate.21',-whenthe dog 27 releases lug 31 the-springs25i actto throw the lower endrof plates21 inwardabove projection 26,.and, as

the frame plate 17 moves downward under the action of cam 16, the cross-head 1 0 and presser foot 9 will be forced downward to bring the bottom of the presser foot into engagement with the heel blank and to force the same, with the rand and metal plate, downward in the holder 7.

In the downward movement of the crosshead 10, the outer member 45 of the presser foot, being in engagement with the rand, or with the heel blank, as the case maybe, will remain relatively stationary,.while the inner member 43 of the presser footwill be forced downward against resistance of spring 49 until the bottom of casting 36 and the bottom edge of the projection 48 engage the upper surface of member 45, whereupon the presser foot, as a whole, in the downward movement thereof, effected by depress 'ing treadle 34, presses the rand against the metal plate, and, in the further downward movement of the presser foot, effected by tripping the machine, presses the heel blank irmly into engagement with the rand, and both into engagement with the convex side of the metal plate 49. In the movement of the p'resser foot by the machine, as distinguished' from the lowering of the presser foot by pressure on treadle 34, the heel blank and mud are forced with great pressure against the metal plate 492, the resistance being afforded by the col umn of randed heel blanks and plates in the logholde'r 4, as indicated in Figure 2, so that all portions of the. rand are pressed into firm engagement with the heel blank, and the crimps in the rand are, to a large extent, pressed flat. Thus, in this operation,

.not only is the rand securely pressed into position on the heel blank, but a high degree of molding or forniing of the rand is effected, as the randed surface of the heel blank is forced to conform to the shape of the convex side of the plate, so that, as indicated above, when the heel blank emerges from the log-holder, it has much the appearance of'having been subjected to the action of a compress.

Asthe presser foot reaches the lower limit of its movement, the plate 41 will engage the projecting ends 66 of the rand andforce them over the cutter 42' to sever such ends flush with the breast of the heel blank.

7 As the lower edge of actuating plate 21 engages the shoulder 26, the plate will be forced upwardly a slight distance, due to the size of the openings 28, and the springs 28 will turn the dog 27 into engagement with the lug 31 As soon as the cams turn to release the pressure on rollers 19, the springs 20 raise frame plate 17, and, consequently, actuating plate 21, and the. resulting pullof the dog'27 on the lug 81 turns h ot omo u i g plat 2,1; ut10 en.- ga'geinent; with the projection 26,. and; whe

the treadle 34: is released, said projection 26 can move upward without engaging the bottom of plate 21.

As the heel blanks are randed in the manner described, they are forced downward in the log-holder 4, which may be of any desired length.

According to another, and the preferred, method of practicing my invention. with the present machine, after the rand has been shaped to position on the plate 4-9 the machine tripped, and the rand and plate forced downward in the holder 7, a pasted heel blank is then inserted in the holder on top of the rand. a plate is put into position on top of the blank, a rand is placed in position on the plate and wiped into heel shape, the presser foot again lowered, and the machine tripped to force the rand, plate and heel blank downward in said holder. By turning the adjusting screws 8 to properly adjust the height of the holder, the downward movement of the presser foot may be caused to force the rand, plate and heel blank downward in the holder to such distance that when the next heel blank and metal plate 49 are placed in position in the holder, the upper edge of the plate will lie flush with the upper edge of the holder.

In either form of practicing my method, the inclined marginal portion 51 of the metal plate forms a very important function, in that it presents a smooth surface for the thin edge of the rand to move over, and thus avoids presenting any obstruction tending to cause the edge of the rand to curl or buckle when being wiped into position on the plate. At the same time, in cooperating with the presser foot, the inclined surface of the plate offers the necessary resistance to the insertion of the rand between the two to cause it to be properly curved or shaped by the recess 55 of the shaper 54.

It will be observed that in practicing my method. the heel blank in the holder is reversed in position as compared with the position of the heel blank in the said Parks method. In other words, in Parks, the heel blank is first inserted in the holder, pasted side up, and then a rand applied thereto with its beveled side up; whereas, in my method, the rand is applied to'the plate with its beveled side downward, and the heel blank applied to the rand with its pasted side down.

While the machine herein shown and described is admirably adapted for the practice of my method, it should be understood that, so far as the practice of the same is concerned, I am not restricted in use to this machine, as any other machine which will enable the rand to be held on the plate, then shaped, and the heel blank applied thereto and pressed into engagement with the rand, would answer the purposes of the invention.
